<p>An ink jet head includes first base (12) second base (14) which are made of a piezoelectric material. The first and second bases are formed with a plurality of first and second grooves in their surfaces, respectively, and are formed with first and second electrodes (36a, 36b) on their surfaces between the first grooves, respectively. The first and second bases also includes side surfaces (12a, 14a) intersecting the surfaces of the first and second bases, respectively. The electrodes are spaced apart from the side surfaces (12a, 14a). The second base (14) is placed on the first base (12) so that the grooves in the first base and the grooves in the second base communicate with each other to define ink pressure chambers (24a, 24b). An insulating layer is formed on the inner walls of the ink pressure chambers (24a, 24b). An orifice plate (25) having orifices (28a, 28b) is bonded to the side surfaces (12a, 14a) so that the ink chambers communicate with atmosphere through the orifices (28a, 28b). <IMAGE></p> |
